Thread route through bobbin.

Seems like a foolproof way to do it.

Downside I think is getting the bobbin tension adjusted. The Juki style is where the bobbin is placed in the top half part of the bobbin assembly, threaded and tension adjusted while still in your hand and then dropped in place. Personally I like being able to adjust the bobbin tension this way as I can do a bobbin tension drop test.

I've read about this drop test but it never occurred to me that the bobbin must  be different to be able to do it. I always go with a try first. Because my hobby uses different types and thicknesses of leather I'll always test on a bit of scrap first to check tension and needle size. I'll always use the 45 degree slide test as a starting point for needle size and adjust if necessary.
